I just read the Facebook market place rules; there is no prohibition on gaming devices.
Well, I have gone round and round with Facebook and it comes down to Zuckerburger and his cronies are covering their butts.
They are tired of being called in front of congress to explain their business practices...
Promoting gambling is NOT allowed on Facebook, rule number 9 in commerce policies:
Gambling
Listings may not promote the buying, selling or facilitation of online gambling for money or money's worth, including digital currencies. Online gambling includes gaming, betting, lotteries, raffles, casino, fantasy sports, bingo, poker and sweepstakes in an online environment.
While rule number 9 doesn't apply to what we do the guy in charge of flagging thinks it does!
I have gotten flagged and warned so many times anything I post there gets flagged. I posted my 1930 Model A for sale and it got flagged. I posted some old fence boards with great patina for building bird houses and I got flagged. I posted a pic of a slot machine with no description but 'cleaning out the garage' and I got flagged...
You might get lucky and sneak through an ad or two but sooner or later the Zuckerburger is going to gig you...
